Most recently, she worked at Guildford Borough Council for a programme which provided a variety of support to families within the local area. It was a rewarding role that gave her a real appreciation for how important good systems, communication, and empathy are when working within communities.

 

When not working, you might find Janine pottering around in her garden – she says, “Although compared to my colleagues I am a rank amateur at that side of things!”
